PUBLISHED JANUARY 27, 1970 PILE YARN PRIMARY BACKING FABRIC l5 [4 THE MOPLASTIC COATING A process for the manufacture of a textile material, such as a pile fabric having a primary backing fabric having other fibers tufted thereinto or otherwise associated therewith and having high resistance to mechanical removal of such fibers therefrom, by depositing on the backing fabric a thermoplastic material such as powdered polyethylene, melting the deposited material so that it adhesively joins and penetrates into but not completely through the backing fabric and, while the material is still in a molten condition, superimposing on the treated fabric a thin sheet or film of a thermoplastic material or other material and thereafter passing the composite material through a pair of pinch rolls heated to such a temperature as to cause the underlying molten thermoplastic to surround the individual fibers on the back of the textile material, whereby such fibers are locked to the backing fabric by the adhesive effect of the plastic material.
